But I do like to ponder the thought of all Google services, or all Amazon services shutting down for 2 weeks. Clearly not as essential, but the impact on the daily life of at least most of the US would at least be noticeable.
I believe these are still the early days of "internet giants". They seem giant now, but with MS, Google, Amazon, and other "giants" aiming to provide much of the structure of not only the internet, but also some of our daily lives (delivery, web, phone, internet access, information/news), I can imagine twenty years from now the reach of these "giants" to be far closer to "essential" then we feel they are now.
Who knows, maybe we will forever be in a cycle of "giants" growing, evolving, and failing without ever becoming essential. I don't know how it will work haha, but interesting to consider.
